318 Build-up Questions

318 will not be fun to drive with big valve heads,the bores are too small.I know some guys would tell you otherwise,but ive tried it myself before.it just so happens i burnt a valve in the 360 heads,and had som 302 casting heads from an 86 ramcharger i bought.just swapping to the 302 heads,with fresh valve job,woke my engine up!it felt like it doubled the power.i couldnt spin a tire with the 360 heads,and now traction is a real problem,even in second gear it will get side ways!
